Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your One drive account to Claude via Composio Connect, enabling it to share project folder with your team, download the latest version of report.docx, check who can access budget.xlsx, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

You can also connect Claude to multiple One drive accounts with Composio.

3. Connect your One drive account

Back in Claude, ask it to connect to One drive or give it any One drive-related task.

For example, ask Claude to:

  • "Share project folder with your team"
  • "Download the latest version of report.docx"
  • "Check who can access budget.xlsx"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your One drive account is ready to use.

What is the One drive Claude Connector, and what's possible with it?

The One drive MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your OneDrive account. It provides structured and secure access to your cloud files and folders, so your agent can perform actions like uploading documents, sharing files, managing storage, and retrieving version histories on your behalf.

  • File and folder management: Effortlessly copy, move, or delete files and folders, keeping your OneDrive organized with just a prompt.
  • Easy sharing and collaboration: Instantly generate secure sharing links for documents or folders, making collaboration with others seamless.
  • File download and preview: Have your agent fetch files or retrieve visual thumbnails for quick previews and streamlined access.
  • Access control and permissions review: Check who can view or edit any file or folder, and manage sharing permissions without manual clicks.
  • Version tracking and quota monitoring: Retrieve version histories for files and monitor your storage quota to stay on top of changes and space usage.

Troubleshooting

1. Why does Claude not use the Composio connector for One drive?

The connector can show as connected, but Claude must use it in each One drive conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to One drive again.

2. Why does Claude show an MCP server error before One drive connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for One drive.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect One drive.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the One drive authorization link not work?

The Composio connector is one server. Your One drive account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the One drive connection.
  • Composio creates a fresh One drive authorization link.
  • Open that link in your browser and finish the One drive sign-in.

4. Why do One drive actions fail after they worked before?

The One drive connection can expire or lose permission.

  • Ask Claude to inspect the One drive connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the One drive account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in One drive.
  • If the action still fails with a permission error, check that the connected account has that permission in One drive itself.

5. How do I switch to a different One drive account?

Claude can manage the One drive connection for you.

  • Ask Claude to disconnect or delete the current One drive account.
  • Ask Claude to connect One drive again.
  • Open the new Composio authorization link for One drive.
  • Sign in with the other One drive account in the browser.
  • After the account connects, ask Claude to retry the One drive task.

6. Why is my One drive connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your One drive connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click and click Clear cache.
  • If One drive tools still do not appear, click , disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect One drive.

FAQ

Frequently asked questions

With a standalone One drive MCP server, the agents and LLMs can only access a fixed set of One drive tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from One drive and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right One drive tools.

Yes, absolutely. You can configure which One drive scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your One drive data and credentials are handled as safely as possible.
